Specification of Letters Patent. I Patentd June 24, 1913,

Application filed May 10, 1911. Serial No. 626,271.

To all whom, it may concern:

Be it known that I. AMBROISE GOUPY, a citizen. of the French Republic,and resident of Paris, France, have invented certain new and usefulImprovements in Aeroplanes, of which the followingis a description.

With the above object in view, the aeroplane includes a frame withplanes pivotally connected thereto and located at, equal distances fromthe frame. The said planes are normally disposed one above the other andmeans is provided for moving the planes edgewise with relation to theframe so that their end portions may be projected beyond each other andso that the planes may be disposed at'desired angles with relation tothe longitudinal dimension of the frame.

In the accompanying drawing Figure 1 is a perspective view of theaeroplane 'made in accord with my invei'ition Fig. 2 is a detail sectionshowing a connection between the lever and the lower plane.

Corresponding and like parts are referred to in the following,description and indicated in the" accompanying drawing by the samereference characters.

The aeroplane includes a frame 1 to which are pivotally attached arms 2.The arms 2 extend transversely and approxi mately vertical across theframe 1. An upis pivoted to the upper ends of he arms 2 and a lowerplane 4 is pi oted -o the lower ends of the said arms. These planes areapproximately at equal distances from the points of pivotal connect-ionbe- ;ween the arms 2 and the frame 1. Arms =3 are pirotally connected attheir inner ends to the frame 1 and at their outer ends are pivotallyconnected with the planes 3 and 4 respectively. Arms (3 are pivotall'yconnected at their ends to the planes 3 .and 4. The points of pivot ofthe arms 22 to the frame. 1 are in .vertical alinement with the pointsof the pivots between the ends of said arms and the planes 3 and 4 whenthe planes are in normal position. i-iny suitable means may be providedfor shifting the plane; 3 and 4 edgewisc and as shown in the drawingsuch a means includes a lever 7, which is pivotatly mounted upon theframe 1, and which is operativelyconnected by means of cables 8 withthelowermost frame 4. The said cables being trained around pulleys 9journaled upon 5? the frame 1. Therefore it is obvious that by swingingthe lever 7 the cables 8 yvill be moved longitudinally whereby the lowermost plane 4 will be moved edgewise under the frame 1. This swings thearms'fl, 6 and 5 whereby the uppermost plane 3 is moved edgewise in theopposite direction from that in which the plane 4 is moved. Therefore itwill be seen that the planes 3 and 4 may bedraw'n toward each other and05 the edge of one plane may be moved in advance of the edge of theother plane. lVhile the planes always remain parallel to each other, thesaid planes as they are moved edgewise as above stated vary intheirangular relation to the frame 1, for the reason that the arms 5 arenot in alinement with each other, while the end portions of the arms 2are inalinement with each other. The relative location of the planeswhe'n75 adjusted from the normal to the abnormal, or operative,position, is due to the location of the pivotal points of the arms, andbecause of there being a slight. lost motion between the arms (3, andtheir I ivots,as indicated at 6* the angle of the anes will vary whenthe arms are rocked from their normal position.

Having described the invention, what is claimed as new is. I

An aeroplane comprising a frame, upper and lower planes normallyparallel with each other, arms pivoted to the frame and the planes,pivots connecting the arms to the frame and to-the planes the saidpivots being in alinement, other arms pivoted to the frame and theplanes, pivots connecting, said other arms to the planes and to theframe, the pivots between the arms and the I planes fitting loosely inthe-arms to provide a slight lost motion and the pivots between saidsecond mentioned arms and the frame being located ant of alinement withthe.

pivets between said arms and the planes, In testimony whereof I havehereunto and means for operating the planes and set my hand in presenceof witnesses.-
